There are different sizes and types of granulators used that process thin to thick plastics; flexible, soft, or hard plastics; unreinforced to reinforced; and so on. Conventional methods of destroying chlorinated hydrocarbon waste include, Removal of Surface Contaminants Using Ionic Liquids, Developments in Surface Contamination and Cleaning: Methods of Cleaning and Cleanliness Verification, Hazardous materials in the form of wastes are a toxic by-product of industrial activity in the public and private sectors. Pyrolysis and incineration operate at over 200 degrees C or 400 degrees F and usually over 1000 degrees F. Such process of waste remediation is known as SCWO or cold combustion. Fly ash composition varies depending on the type of coal used and the incineration process in place at the power plant. There are several commonly used methods of sludge treatment, including long-term storage (in lagoons), lime stabilization, digestion (aerobic or anaerobic), air drying, thermal drying, and incineration or gasification (for energy recovery).

Oxygen addition and temperature is controlled to specified temperatures to ensure complete burnout and destruction. It is a type of thermal treatment carried at very high temperature.

Conventional methods of destroying chlorinated hydrocarbon waste include thermal incineration, supercritical water oxidation, direct chemical oxidation, photochemical oxidation, and solvent extraction among many different treatment techniques [352]. Each of these techniques has disadvantages and limitations, including high capital, installation, energy, and operating costs, public acceptability, handling and disposal of the process wastes, and not environmentally benign. The solid waste contains combustible matter, non-combustible matter and moisture. Due to the low levels of metals in sludge, application rates are governed in practice by maximum nitrogen application rates (250 kg/ha yâ1 or 500 kg/ha yâ1) and to balance phosphorus addition with crop off-take. van Deventer, in, Fly ash composition varies depending on the type of coal used and the, Fernández-Jiménez & Palomo, 2005; Swanepoel & Strydom, 2002, Fernández-Jiménez, Palomo, Sobrados, & Sanz, 2006; Fernández-Jiménez, Puertas, Sobrados, & Sanz, 2003, Valcke, Sarabèr, Pipilikaki, Fischer, & Nugteren, 2013, Lloyd, Provis, Smeaton, & van Deventer, 2009; Oh, Monteiro, Jun, Choi, & Clark, 2010, DurdziÅski, Dunant, Haha, & Scrivener, 2015, Rickard, Williams, Temuujin, & van Riessen, 2011; Ward & French, 2006, Henderson & Fleet, 1997; Zhang, Provis, Zou, Reid, & Wang, 2016. Fig. Granulators are predominantly used. A granulator that handles soft plastics will not work well when granulating hard plastic. For this reason sludge has historically been applied to agricultural land as part of an integrated farm management plan. Dioxin and furans are carcinogenic and can cause birth defects. Ex situ thermal treatment, including thermal desorption and incineration, relies on heat to remove contaminants of concern (COCs) from contaminated media, such as soil and sediment1. See Fig. (2008), Kikuchi (1998), Korving (2011), Kutuk and Aksoy (2013), Lowe (1988), Malerius and Werther (2003), Murakami et al. Thermal Desorption and Incineration .
